How does a typical transaction through Mastercard work?
- In a typical transaction, an account holder purchases goods or services from a merchant using a Mastercard product. After the transaction is authorized by the issuer, the issuer pays the acquirer an amount equal to the value of the transaction, minus the interchange fee and other applicable fees.
- Interchange fees reflect the value merchants receive from accepting Mastercard products and play a key role in balancing the costs and benefits that consumers and merchants derive. These fees are collected from acquirers and paid to issuers to reimburse the issuers for a portion of the costs incurred.
- The merchant discount rate is established by the acquirer to cover its costs of both participating in the four-party system and providing services to merchants. The rate takes into consideration the amount of the interchange fee which the acquirer generally pays to the issuer.
- Through Mastercard’s core payment network, they enable the routing of a transaction to the issuer for its approval, facilitate the exchange of financial transaction information between issuers and acquirers after a successfully conducted transaction, and settle the transaction by facilitating the exchange of funds between parties via settlement banks chosen by Mastercard and its customers.
- Mastercard’s core payment network switches transactions throughout the world when the merchant country and country of issuance are different (“cross-border transactions”), providing account holders with the ability to use, and merchants to accept, Mastercard products and services across country borders.
- Mastercard guarantees the settlement of many of the transactions from issuers to acquirers to ensure the integrity of its core payment network. However, it does not guarantee payments to merchants by their acquirers or the availability of unspent prepaid account holder account balances.
- Mastercard’s core payment network features a globally integrated structure that provides scale for its issuers, enabling them to expand into regional and global markets. It is based largely on a distributed (peer-to-peer) architecture that enables the network to adapt to the needs of each transaction.
